No: Aneurysms form most commonly as a result of a weakened area of the blood vessel wall which may become enlarged (forming an aneurysm) over time. High blood pressure and smoking may accelerate this process but it is not related to trauma.

Sometimes: Rarely, head trauma can damage a blood vessel (such as in a dissection) and cause a brain aneurysm. Most of the time, head trauma does not lead to the formation of brain aneurysms.

No: Cerebral aneurysms are congenital weakening of the lining of blood vessels. They are present in about one in a hundred patients. The incidence seems to increase as we grow older.
